Energieffektivisering i ett reningsverk för skogsindustriellt avloppsvatten genom förfällning av extraktivämnen

Pulp- and papermills expend vast amounts of water in order to produce pulp, paper and cardboard. Hence, they alsocreate vast amounts of waste water which has to be cleaned before it can be released into the receiving body of water. Insuch a wastewater treatment plant, tremendous amounts of energy are expended by the aeration in the biologicalcleaning process. This aeration is necessary to supply the microorganisms that shall decompose organic material withoxygen, which they need for their metabolism. The transfer of oxygen from the gas phase to the liquid phase isprimarily inhibited by surface-active substances in the waste water like resin acids or fatty acids.

Vetenskaplig publicering i förändring ? En fallstudie av en svensk högskolas implementering av ett öppet digitalt arkiv

Since the beginning of the 21st century the Open Access-movement, which advocates free online distribution of scholarly information, has gained momentum. Authors can provide Open Access to their work in two main ways: by depositing a copy of their research output in an e-print archive and by publishing in Open Access journals. During the past few years, universities and other research institutions throughout the world have established institutional repositories to manage, preserve and provide access to the intellectual output of the university/research institution. The purpose of this master?s thesis is to describe the implementation of an institutional repository at the Swedish University College of Borås.

Social hållbarhet och attraktionsfaktorer i en urban kontext. Fallstudie över Malmös nya stadsdel Hyllie

Do new, attractive neighborhoods meet the requirements of being socially sustainable? This essay is based on the potential conflicts between the pursuit of social sustainability, while the theory of the creative class influence city planning. Social sustainability is difficult to measure, but implies broadly that everyone should have equal rights and opportunities. A city or region that aims to attract a certain type of people by providing what they ask for, might pay less attention and spend less resources on the rest of the population. Socially sustainable - for whom? The new district Hyllie in southern Malmö stands in focus, and the paper seeks to identify how different operators in Malmö defines the concept of social sustainability, how it is implemented in the design of Hyllie, and if any potential conflicts may arise.Interviews with the following informants; representants from the Office for City Planning in Malmö, the nonprofit organization Sustainable Development Skåne, the Commission for a Socially Sustainable Malmö and the company Skanska Öresund have constituted the main methodology, among with reading and analyzing existing documents and policies relating to the development of Hyllie.

Effekten på nedbrytningen av rötter vid tillförsel av ammonium sulfat i en granskog i sydvästra Sverige

Decomposition of organic matter is a critical process in the ecosystem, which involves many essential biotic and physical parts. Decomposition is therefore an important process both above and below ground. The rate of decomposition is dependent of many environmental factors for example: pH, moisture and supply of oxygen. The decomposition can therefore be affected by large scaled environmental influences, such as acidification and climatic changes. The root litter in the forest is in different ways affected by acidification, liming and manuering.

Livets sköra tråd : Dop och fadderskap i Bottnaryd och Ulricehamn 1781 - 1783

?Life on a delicate thread?Baptism and godparenting in Bottnaryd and Ulricehamn 1781-1783The aim of this study is to discover if there were differences between the baptism traditions maintained in a typical rural parish and in an urban town parish in the period 1781-1783 and to suggest possible reasons for any differences found. Baptism records from rural Bottnaryd parish and the town of Ulricehamn were studied and compared. In both communities, parents were anxious to have their child christened on the day of birth or the day after. They did not want to wait until the following Sunday, as church law prescribed. Infant mortality was high and if the child died before it was christened, it would not go to heaven.

Bostaden och de boende

AbstractWe all have experience of dwelling, which means that everyone can have an opinion about the architecture of the dwelling. Today the building companies do not have time enough to investigate which architecture qualities their clientele ask for in their apartments. JM AB use to call their apartments ?generous city apartments?. But do these apartments fulfill the needs of their dwellers? And what would the apartments look like if they were designed according to the wishes of the dwellers? When JM AB get knowledge about the dwellers needs and wishes they can make even better apartments for their future customers.The purpose and the objective with this report are to draw up proposals for tenant owner flat.

Enumerating Atlantic salmon smolt production in River Vindelälven based on habitat availability and parr densities : consequences of using different density estimation methods

Habitat mapping was conducted in the main stem of River Vindelälven in the autumn of 2009 along the salmon distribution area. The aim was to estimate the quantity of potential reproduction areas, including spawning and juvenile rearing habitats. The mapping included 61 km of various stream sections along the river length of 269 km. The total area of stream habitats was estimated to 647 ha of which 396 ha (61%) were considered as either potential or optimal juvenile nursery habitats. The area of these two habitat classes were used to estimate the smolt production in the river by using electro fishing densities of juveniles (0+ per 100 m2).

E-förvaltningens roll i främjandet av demokrati. En fallstudie om offentlig förvaltnings relation till demokrati med stöd av IT

Information technology (IT) with its enormous capacity involves more and more in our daily activities and public sector is using IT to make their activities more efficient. The government goal with electronic government (e-government) among other things is increasing the availability and service to the public as well as improving the democratic process. Democracy can be strengthened by involving citizens in public decision making process but this goal has not been achieved yet and the development of e-government has mostly been focused on improving efficiency within administration and electronic services (e-services). Promoting the democratic process has been postponed in the development of e-government because of the lack of political commitment and decision. Digital divide is also preventing public sector to promote democracy with the support of IT.

Trä som fasadmaterial ? behandling och beständighet

Since prehistoric time man has used wood to build their environment. The material?s availabilitycombined with its good mechanical properties has often made it the material of choice. Like allmaterials exposed to natures degradative processes the properties of wood decreases over time.Rot, UV radiation and attacks by insects and pests damage wood if not protected. Since we wantwhat we build to consist, optimizing our building materials durability is of great interest.Techniques and methods for increasing the endurance of wood have been developed in severaldifferent places and for a long time.

Habitat use and ranging behaviour of GPS tracked juvenile golden eagles (Aquila chrysaetos)

Throughout its wide distribution in the northern hemisphere, the golden eagle occurs in a diverse range of environments, e.g., mountainous, forest and open areas. The literature on juvenile golden eagles is limited, and this study provides further knowledge on habitat use and ranging behaviour during the post-fledging period in boreal Sweden. A total of 14 golden eagle juveniles were tagged with GPS transmitters during 2010 and 2011, and nine could be followed during the entire post-fledging period from fledging until migration. The juveniles fledged at the end of July and beginning of August and initiated migration during October and beginning of November. The length of the post-fledging period, until migration started, ranged from 49 to 97 days. During this period, the juveniles? distance from their natal nest and their GPS height increased with time as their flying abilities developed.

Fungiciders påverkan på kvävehalten i höstvete : hur påverkar användandet av fungicider utnyttjandet och inlagringen av kväve i höstvete?

A common perception is that fungicide treatments increases yield, but that the nitrogen of the particular grain is diluted so that the overall removal of grain nitrogen from the field remains unchanged. The aim of this paper is to demonstrate that a healthy crop reduces the risk of nutrient loss from agricultural land. The results from genotype and plant protection trials often show constant nitrogen content in the grain, although the yield has been increased. Results from such experiments are therefore processed in order to confirm this and show that it is no statistically significant difference between the protein content (and also nitrogen content) in crops which have undergone fungicide treatment compared to crops which remained untreated. The trials processed have been carried out in the southernmost part of Sweden and are distinguished to concern winter wheat production.The explanation to the results is that a healthy crop is able to maintain the biological functions of the plant in a more efficient way than a crop damaged by a fungal infection.

Som man betalar f?r man banta. En kvalitativ analys av hur traditionella nyhetsmedier gestaltar Ozempic

In the past year, Ozempic has been observed internationally, as well as in the Swedish press, due to its rapid rise in popularity, its off-label use for weight loss, and the ethical and societal debates surrounding availability and impact. The purpose of this study is to examine how Ozempic is portrayed in the four largest Swedish daily newspapers: Svenska Dagbladet, Dagens Nyheter, Expressen and Aftonbladet. The aim of the thesis is to identify the frames within which the drug is described to acquire knowledge of how it influences public perception of it. Every article published between the first of March until the first of November has been included in the study, if it bottoms in the defined phonomenon. The method used is a qualitative text analysis in consideration of Entman?s framing theory, which is focusing on identifying dominant themes, problem definitions, proposed solutions, and the actors attributed responsibility in the coverage of Ozempic in Swedish press.
